Light can travel faster than light! Time is getting more and more untimely. I will not link to the NYT article, however, because it bugs people to join their NY Times club just to read some article. The jist of the article had to do with light waveforms in a special optical fiber that seemed to bounce back out before the signal entered the fiber.
Since the light itself was slowed down to something like 40 mph, rather than its usual 490 million mph, there was some question whether time wasn't bent in some way that precluded measuring things accurately, in my opinion. Still, there was an effect that wasn't expected and part of the waveform input to the fiber was momentarily subtracted by the reflected waveform (something that happens to waveforms a lot) in that funny timeframe.
